We had a new tutorial on representational similarity analysis come out recently. Led by @xallysie.bsky.social with Ruoying Zheng and @chujunlin.bsky.social
This technique lets you compare patterns across diff types of measures (eg correlate correlation matrices), super flexible

Our new study shows that living in states with higher levels of structural sexism was associated with worse cardiovascular disease outcomes for both men and women, especially for diabetes and stroke.

There is a robust link between intergroup contact & reduced prejudice, but does contact actually cause a reduction in prejudice?
Across multiple longitudinal data sets (N > 20,000), very few people reported increased contact AND reduced prejudice.

Hostile and benevolent sexism are both on the decline in 1,097 studies, N = 339,740 since 1996.
Note that "3" on these scales is already a neutral response. Even bigger progress in countries with more hostile sexism.

How do we figure out who will accept or reject us in a new group?
We show that people generalize relational value across friendship ties—forming a network gradient of approach & avoidance.
